High Power 48v-72v 3000W-5000w Electric Scooter Ebike 80A Sabvoton Controller

Product Information

So far, I tested all those controllers on a 72V 35Ah lead acid battery, on my electric motorbike, with 16 inches 3000W QS V3 high speed motor. If you don't want high top speeds, but you want high voltage, what are you doing? Every reduction gear stage robs you of several percent efficiency. For a mid drive it's most efficient with just 1 stage, chain to drive gear. If you don't need high speed, then you don't need high voltage, you need a motor that has the correct KV. For that matter if you did want high speed you could do it with low voltage, it would just require more amps. Wish I could help you with the #30h error. I think others have reported that error before. Any good results? It's special design for QS brushless motor controller for Conversion Kits, which can match with QS HUB MOTOR Rated Power 3000W-4000w.if you want to match with new brand motor, some parameters should be tested by yourself.

So your magura is for sure different than my throttle. Maybe sends signal range like 0,2-4,0 V , so you go TPS low 5% and TPS high 80%. Mine throttle sends signal lets say like 0,9-4,0 V , so I go TPS low 20% and TPS high 80%. What number did you program into the TPS dead low setting of the Kelly controller parameter ? My throttle response on my Kelly 7218s was also poor, and I was told to change the TPS dead low setting to " 5" . I'm trying to find other Kelly users that want to work together and figure out what all these programmable paramaters mean and what is the best settings to input for them, for best overall performance of ones ebike setup. The Kelly manual isn't very understandable IMHO.[/quote] The cover has been slightly changed, but the function haven't changed. Customers can buy them according to their needs.Amberwolf, some of those are good reasons, but they don't really apply to what this controller is designed for, medium power hub motors. Field weakening. I believe it's settable from 0-100A. I need to do some more testing on how much it effects my top speed but I think I saw 53mph with it set to 50A, but I can't remember for sure so I'll have to go test again after I recharge the battery. Nice thing with field weakening is that it only decreases the efficiency when it's in use, which is usually only when you make those short high speed sprints, not at normal cruising speed. So after I tried out the controller for a few weeks I decided that I wanted to sell them, but I wanted some additional features. I saw that the software had a display for motor temperature, but I didn't see any settings for it. There are settings for over temperature of the controller, but no motor temp. It takes only 3 minutes for the motor to be well matched on its bestelectronic angle at the first time. You have to understand here that those two controllers have a very different technology. Square wave for the Kelly and Sinewave for the sabvoton. Kelly is also doing square wave controllers, but I never have the opportunity to own one so far.

I also tried a big 250A continuous Lingbo sinewave controller. It seemed far inferior to me than the sabvoton. Lots of throttle lag, weird regen, seemed somewhat less powerful or barely equivalent to a 150A sabvoton, seemed very inefficient in terms of power consumption, the programming software wasn't good.... So far the sabvoton remains my absolute favorite. It takes only 3 minutes for the motor to be well matched on its best electronic angle at the first time. I haven't tried it. Physically this controller is larger and should have a higher continuous wattage rating based on construction, but burst current wise both seem to be the same 12kW which means performance will be about the same for acceleration/wheelies etc, what most people want. Ebikes tend to be an easy load to drive because the motors are usually high inductance and only take high current bursts for a few seconds before they settle down to low current levels. You get more features with the Adappto, but that's reflected in the pricing. I have a customer who uses Cromotors as mid drives in a +3000lb vehicle so it's hard on controllers. They even managed to get one road legal by sustaining >20mph for over 1 mile. For commercial use I need a high quality controller than what the Xie Chang was providing and 8-12kw bursts make for a really fun bike.

Full disclosure, I will be selling these units because I like them. I will start a separate thread in the appropriate for sale section, so please keep that discussion in that thread. for my maguara twist throttle, I was told to set the TPS dead low to 5% .....because at a higher setting, the throttle would not send power to the motor until it had been turned 1/2" of twist....which I did not like it that way.[/quote] Sabvoton 72V 150A eBike Scooter Controller Stealth Bomber SVMC72150 V1 V2 Support Plug and Play Display

If I’m successful with a repair I’ll provide details. Unfortunately I’m not able to attempt again until November. I’ve been through 3 tft displays. I’m also using a Sabvoton controller. I find that they die when the battery voltage is cut while riding, i.e BMS low voltage cell protection, CB accidentally switched off, negative cable unplugged. I’ve tried repairing; found that Q1 and Q4 were dead plus a diode. Both transistors are rated for 100V. Must be more failed components than this as display is not fixed yet. The precise current ring can provide accurate torque input to meet the requirement of large torque output during vehicle starting and climbing. Also maybe I d like to know, which model do you have, and if you have any other issues with Sabvoton ? [/quote] The slow wind motors are saturated at low amps. Remember that I'm pairing this controller for use with a Cromotor since I am always asked by customers what controller I recommend.A: Delivery by Express will take 3-5 working days to reach your door. Delivery by sea will take 15-35 days to reach your port. The motor torque ripple will be reduced to the minimum, so as to ensure electric vehicle to run without any noise and vibration, smoothly, and comfortably. You can program the Sabvoton Controller 72200 by both Computer and Smart Phone (iPhone and Android). Sabvoton Controller 72200. The controller enjoys high efficiency due to space vector converter control algorithm which can effectively reduce the temperature rise of controller and extend battery life mileage Sabvoton controller only design sine wave type controller so far, it’s brushless DC controller, 120 degree phase angle. Generally, we matched it well with QS Motor, if you want to match with new brand motor, some parameters should be tested by yourself.
